“…The enlargement of the spleen due to long-term hypersaline stress can be significantly improved by β-glucan supplementation in the diet regardless of concentrations. β-glucan (0.1%) in the diet also can decrease RSW in O. niloticus under diazinon stress [46]. Cytologically, the spleen is the largest lymphoid organ and an immunocompetent organ in teleost that is rich in melano-macrophages for phagocytosis in the immune response [47].…”

Long-term exposure to hyperosmotic environments can induce severe immune damage and increase risk in tilapia breeding. As an effective immunoregulator, β-glucan has attracted extensive attention in nutritional research and given rise to high expectations of improving health status and alleviating organismal damage in tilapia, Oreochromis niloticus, in brackish water. In this study, an 8-week cultivation experiment was conducted on tilapia fed a basal diet or diets with β-glucan supplementation in freshwater (control) and brackish water. Growth performance, hematological aspects, immune cytokine expression, and the intestinal microbiota of tilapia were analyzed. The results indicated that supplementation with β-glucan significantly reduced the enlarged spleen of tilapia resulting from hypersaline stress. Tilapia fed β-glucan showed significantly-greater decreases in the red blood cell count, hematocrit, red cell distribution width, platelet count, and plateletcrit than those fed the basal diet. β-glucan significantly decreased the high expression of immune-related genes in the spleen induced by hyperosmotic stress. In the intestine, the high migration inhibitory factor-2 (MIF-2) and IL-1β gene expression induced by hypersaline stress was significantly reduced. β-glucan supplementation also significantly increased the abundance of beneficial microbiota such as Lactobacillus, Phycicoccus, and Rikenellaceae. Therefore, dietary β-glucan supplementation can significantly reduce spleen enlargement and improve immune function in tilapia in brackish water. β-glucan intake can also optimize the intestinal microbiota of tilapia in brackish water and improve fish health.

“…Also, in Oreochromis mossambicus, dietary supplementation of b-glucan (10 mg g À1 for eight weeks) enhanced ammonia (100 mg L À1 for 1 week) stress tolerance (Divya et al 2020) as previously reported in Japanese sea bass (ChunYu et al 2013). Studies also reported the protective effect of b-glucan against other abiotic stressors, including crowding stress in Nile tilapia (Dawood et al 2020f;de Souza et al 2020), hypoxia stress in Atlantic salmon (Rodr ıguez et al 2016) and yellow croaker (Zeng et al 2016), Furthermore, administration of b-glucan protected several fish species against heavy metal and pesticide toxicity via enhanced immune, antioxidant and inflammation defences (Zeng et al 2018;El-Murr et al 2019;Abdelhamid et al 2020;Dawood et al 2020g;Mokhbatly et al 2020). A recent study in hybrid giant tiger grouper demonstrated that dietary combination of b-glucan and oxytetracycline exerts synergistic immunostimulatory effects and provided better protection against bacterial infection than those fed oxytetracycline alone (Lee et al 2020).…”

Over the last few decades, the demand-driven growth in aquaculture has been tremendous due to development and adoption of cutting-edge technologies and production systems such as intensification and high input aquaculture. This growth, however, has witnessed an insurgence of various environmental and husbandry-related stressors posing major challenges to the aquaculture sector limiting its further expansion worldwide. These stressful conditions impair the health of cultured animals and predispose them to diseases resulting in economic losses. Hence, optimizing the stress resilience of the cultured species is paramount to ensure sustainable development of aquaculture sector. Addressing the concerns of stress mitigation in aquaculture, a plethora of research investigations have been intensively carried out all over the world targeting the management of cultured environment as well as cultured species. Among various mitigation strategies, dietary interventions appear to be pliable and a sustainable approach to develop immunocompetence and stress resistance in fish as requirement of several nutrients may increase under stressful conditions. The suboptimal and/or excessive levels of several essential and non-essential nutrients modulate the immune response and stress/disease resistance. Hence, the present review is an inclusive and informative compilation of dietary interventions for management of stress in aquaculture. This review highlights the stress-mitigating roles of different nutritive and non-nutritive compounds/additives such as amino acids, essential fatty acids, phospholipids, vitamins, minerals, carotenoids, different synthetic chemicals and biological derivatives from bacteria, yeast, fungi, algae, plants and animals as a promising stress management strategy to enhance the overall performance of the cultured species.

“…When the pH was 7, the dosage was 5.0 g/L, and the adsorbent was BC3, the removal rate of diazine reached 98.96%. Similarly, a large amount of agricultural waste can be used for pesticide removal, such as corn stalks, rice stalks, discarded orange peel, almonds, wood derivatives, birch and Norwegian spruce, bamboo flakes, and even poultry dung, all of which have achieved good results ( Liu et al, 2015 ; Cederlund et al, 2016 ; Mandal et al, 2017 ; Suo et al, 2019 ; Abdelhamid et al, 2020 ).…”

Diazinon is an organophosphorus pesticide widely used to control cabbage insects, cotton aphids and underground pests. The continuous application of diazinon in agricultural activities has caused both ecological risk and biological hazards in the environment. Diazinon can be degraded via physical and chemical methods such as photocatalysis, adsorption and advanced oxidation. The microbial degradation of diazinon is found to be more effective than physicochemical methods for its complete clean-up from contaminated soil and water environments. The microbial strains belonging to Ochrobactrum sp., Stenotrophomonas sp., Lactobacillus brevis, Serratia marcescens, Aspergillus niger, Rhodotorula glutinis, and Rhodotorula rubra were found to be very promising for the ecofriendly removal of diazinon. The degradation pathways of diazinon and the fate of several metabolites were investigated. In addition, a variety of diazinon-degrading enzymes, such as hydrolase, acid phosphatase, laccase, cytochrome P450, and flavin monooxygenase were also discovered to play a crucial role in the biodegradation of diazinon. However, many unanswered questions still exist regarding the environmental fate and degradation mechanisms of this pesticide. The catalytic mechanisms responsible for enzymatic degradation remain unexplained, and ecotechnological techniques need to be applied to gain a comprehensive understanding of these issues. Hence, this review article provides in-depth information about the impact and toxicity of diazinon in living systems and discusses the developed ecotechnological remedial methods used for the effective biodegradation of diazinon in a contaminated environment.
